4. Tokyo, Japan: A tech-obsessed city where robots come to life
Tokyo is stepping up its smart city game as it prepares to host the 2020 Summer Olympics. This very clean but densely populated metropolis was named the most livable city in the world in 2015** and routinely tops the smart city rankings.
Of all the region’s futuristic cities, Tokyo might be the most fascinated with innovation and electronics, which can be experienced live at the famous Robot Restaurant in Shinjuku, where larger-than-life automatons backed by giant LCD screens flash, move and interact with the audience. Feeling lost? The tourism board’s free Tokyo Handy Guide App offers maps that can be used offline and helps visitors to easily explore the city on foot.
